San Leandro, Calif., a corporation of California Application January ,7, 1958, Serial No. 707,527 3 Claims. (Cl. 20-11) The present invention relates in general to improvements in a horizontal window of the type which includes in'a unitary frame-a fixed sash, and a sliding sash movable between closed and open positions relative to a window opening or vent; the window frame and the sash frames being designed for construction frombut not limited tomet-allic extrusions of aluminum alloy or the like.

' The major object of the present invention is to provide, in a window of the type described, a novel rectangular frame for the reception of the fixed sash and the sliding sashandif desireda framed screen which exteriorly overlies said window opening or vent.

Another important object of the invention is to provide a window frame wherein the metallic extrusions which constitute the sill, header, and side posts includein integral relationthe elements or parts which serve to mount the frame in place, as well as the primary elements or parts which define the mounting or supporting assembly for the sashes and the screen.

Still another object of the invention is to provide a horizontal window wherein its frame includes-with sash receiving channelsa novel drainage arrangement by means of which water from rain, condensation, or the like drains directly from each bottom channel directly onto a sloping sill, and without transfer from a rear bottom channel to a front bottom channel and thence to the outside, as has been a prior practice and which frequently resulted in an undesirable blow-back of water to the inside of the window.

. It is also an object of the invention to provide a horizontal window of the type described wherein the sliding sash, and the screen when included,'are each associated with certain parts which prevent unauthorized removalof said sash and screen from exteriorly of the window.

A separate object of the invention is to provide a novel self-catching latch between the center post of the window frame and the sliding sash whereby to automatically lock the latter when the same is slid to closed position.

A further object of the invention is to provide a horizontal window wherein the sliding sash is mounted for quiet, easy, non-binding movement, without metal-tometal contact, between closed and opened positions, and a window wherein both sashes are effectively Weathersealed.

A still further object of the invention is to provide a horizontal window which is designed for ease and economy of manufacture, and ready and convenient installation; the Window-as installed-presenting a very attractive appearance, both from exteriorly and interiorly' thereof. a

An additional object of the invention is to provide a practical, reliable, and durable horizontal window with 2,918,706 Patented Dec. 29, 1959 Fig. 3 is an enlarged vertical, transverse section-foreshortenedtaken on line 3-3 of Fig. ,1,

Fig. 8 is an enlarged fragmentary elevation of the upper and outer corner of the screen, and shows the swingable locking arm.

Referring now more particularly to the drawings, and to the characters of reference marked thereon, the window comprises a horizontally elongated, rectangular frame, indicated generally at 1 1n Fig. 1; such frame being comprised of a sill, a header, and side posts, indicated at 2, 3, and 4, respectively. The side posts extend betweenand are secured at a miter joint in connection withthe sill and header in the manner as will subsequently appear.

The sill 2 includes a sill plate 5; the header 3 includes a header plate 6; and the side posts 4 each includes a side plate 7. Relative to the rear edge, the sill plateS slopes downwardly and outwardly; the header plate 6 slopes upwardly and outwardly; while the side plates 7 slope laterally and outwardly, all whereby the frame 1as a whole--is of greater rectangular dimension at the front than at the rear.

Each of the plates 5, 6, and 7 is part of an integral metallic extrusion, of an aluminum alloy or the like, and each includes a central, laterally outwardly projecting, full-length attachment or nailing fin 8 adapted to lie in abutment againstand to be nailed, as at 9, to-the related wooden member M of the framed window receiving opening; the frame 1 thus being fixedly supported in such opening.

In addition to the nailing fin 8, each of the plates 5, 6, and 7 is formed at its rear edge with a laterally, outwardly projecting finish flange 10, and at its front edge with a laterally, outwardly projecting finish flange 11. When the window is installed, the corresponding inside finish 12 is run against the flange 10, while the exterior material E of the building structure is run outwardly of the nailing fin 8 between the latter and the flange 11.

Also, at the front edge the sill plate 5 and the header plate 6 are each formed with a trim and drip flange, indicated at 13 and 14, respectively.

The metallic extrusions, which include the plates 5, 6, and 7, and the other parts above described, also each embody-in the same longitudinal vertical plane as the the corresponding flange 15 and extends full width of the frame in forwardly projecting, spaced or over-hanging relation to the sill plate 6.

Similarly, a horizontal, U-shaped, downwardly opening channel 22--defined at the rear by the parting rail 17, and includinga top 23 and a front 24--is formed integral with the corresponding flange 15 and extends full width of the frame in forwardly projecting, spaced or underhanging relation to the header plate 6.

Likewise, vertical, U-shaped, laterally opening channels 25 and 26 are formed in connection with the flanges 15 of the side plates 7; extending full height of the frame and projecting forwardly in spaced relation to said side plates 7. The channels 19, 22, 25, and 26 are all disposed in the same longitudinal vertical plane; being miter-fit at adjacent ends.

As each of such channels is spaced from the related plate of the frame, and as such channels terminate at the front in a plane. which in' effect recesses them, a very attractive appearance is attained. Additionally, the spacing between the bottom 20 of the U-shaped channel 19 and the sill plate. provides for an important functional feature which will hereinafter be described.

Centrally between opposite sides of the frame 1 the latter includes a meeting or center post, indicated at 27, which extends vertically betweenand is secured to the front 21 of channel 19, and the front 24 of channel 22; such meeting or center post 27 including a full-height, rearwardly extending, stop flange 28, whichin front to rear extent-spans across the channels 19 and 22.

A fixed rectangular sash, indicated generally at 29, includes a pane of glass 30 retained in a channeled rectangular frame 31' by a suitable endless seal 32. The rectangular sash 29 occupies a fixed position in the frame 1, engaging at the bottom in the channel 19, at.

the top in the channel 22, at its outer side in the channel 25, and at its inner side back of the center post 27 in substantially abutting relation to the stop flange 28.

The fixed sash 29 is supported in the channel 19' and above the bottom 20- thereof, by a horizontal shoulder 33 which projects inwardly from the front 21 a distance below its upper edge.

Tubular seals 34, seated in the parting rails 16, 17, and 1S, bear in sealing relation against'the adjacent'portions of the channeled frame 31 of said fixed sash 29.

Inthe opening or vent defined by the vertical channel 26, the stop flange 28, and the corresponding or spanning portionsof the channels 19 and 22, a rectangular screen is engaged; such screen being indicated generally' The screen 35 comprisesa sheet of wire cloth 36 car ried in a rectangular frame 37 which abuts at one side against the stop flange 28, but with the other side adjacent but slightly short of the channel 26.

At the bottom the frame 37 engages in' the channel 19, while at the top said frame projects upwardly into the channel 22; such frame 37 being supported in channel 19 a distance above the bottom 20 by a horizontal shoulder 38 formed on, and projecting inwardly from, the front 21 of said channel 19.

The height of the frame 37 of'screen 35 is such that when said frame rests at the bottom on horizontal shoulder 38, the top of the frame extends only part way into the channel 22. This is for the purpose of permitting the frame 37 to be raisedsufficient to escape the channel 19, whereupon the screen 35 can be swung outwardly at the bottom and pulled downwardly for removal.

However, removal of the screen 35 is normally prevented by means of a swingable locking arm 39 pivoted, as at 40, to one side of the frame 37 on the back and adjacent but short of an upper corner.

The arm 39 includes a finger-piece 41, whereby said arm may be swung from its horizontal, dotted-line position of Fig. 8 to its vertical, full-line position as in such figure; the arm in such latter position abutting, at the top, under the parting rail 17, which effectively locks the screen 35 against upward movement, and which is.

necessary to effect its removal. Thus, no one from outside of the window can remove screen 35, and-by reason of the relatively high position of the locking arm 39it is not readily accessible to children from inside of the window.

Rearwardly of the channel 19 there is another horizontal, full-width, upwardly opening channel 42 defined at the front by the parting rail 16, at the bottom by the corresponding portion of the sill plate 5, and at the rear by a laterally inwardly extending flange, 43 which projects in integral relation from said sill plate 5.

A similar but downwardly opening channel 44 is'formedrearwardly of the channel 22; said channel 44 being defined at the front by the parting rail 17, at the top by the corresponding portion of the header plate 6, and at the rear by a depending flange-45.

The full-width channels 42 and 44 communicate at their ends with, vertical, laterally inwardly opening channels 46 and 47 formed with the side plates 7; such channels. 46 and 47 being defined at the front by theparting rails 18, at the bottom. by the corresponding portions of said. side plates 7, and at the rearby laterally inwardly project-- ing flanges48.

At the miter-cut and matching corners of the frame 12 the sill 2, header 3, and side posts 4 are secured together by a right-angle connector 49 disposed in each such corner within the confines of the adjacent end portions. of the related ones ofthe channels 42, 44, 46, and 47.. The legs of such angle connectors 49 are secured byheaded screws 50' which extend through the plate-which forms the bottom of the corresponding channel; such connectors 49 at the opposite edges thereof being engaged'in: locator grooves, the latter all being indicated at 51. With this arrangement the sill2, header 3, and side posts 4'are; all secured together in an effective rigid andv unitaryassembly.

A. sliding rectangular; sash, indicated. generally at.52, isreceived in horizontally slid able relation at the bot-tom: in thechannel42, and at the top in the channel 44; the bottom. of said. sliding sash 52 resting on, and being sup.- ported by, a horizontal, full-width sash track 53 formed integral with the flange43 and extending into said channel; 42; the bottom leg of the right-angle connectors 49, in. the lower corners, extending beneath such sash track.

The sliding sash 52 is comprised of a pane of glass54 carried in a channeled rectangular frame 55, with an endless seal 56 securing. said paneof glassin such frame 55. At the bottom thereof the frame 55 of the sliding sash. 52 is fitted with a molded nylon slide 57 which rides: on the sash track 53 as well as against the adjacent part of the flange 43. Similarly, at the top of said frameSS. it is provided with another such slide 58 which has engagement with the adjacent part of the flange 45.

Atthe front and allabout the same the frame 55 is. fitted with a weather seal or strip 59; the lower and upper horizontal runs of such strip 59 hearing in sliding engagement with the parting rails 16 and 17, respectively, while the vertical runs of said strip 59 are adapted for bearing engagement with the related one of the parting rails 18, dependent on whether said sliding sash 15 isin its closed: position rearwardly of the screen 35, or in its open posi-' tion.

At one side thereof the sliding sash 52 is formed with a vertically extending, rearwardly'projecting, full height, finger engaging flange 60 by means of which said sliding. sash 52 can be readily manually shifted between closed. and open positions.

The sliding sash 52 is releasably securedin closed position, as in Fig. 4--by a locking unit, indicated gen,- erally at 61; such locking unit comprising the following:

On the side of the frame 55 which lies generally to the rear of the meeting or center post 27 when the sliding sash 52 is in closed position, said frame 55 is formed, with a. full-height, forwardly extending flange 62 which. lies between the parting rails 16 and 17, while the stopflange 28 of post 27 has a cor-responding rearward extension 63 also disposed between said parting rails; the extension 63'being spaced laterallyin the directionofsaidv sliding sash-from flange 62.

At the freeends, thereof. the flange. 62 and rearward;

extension 63 are formed with right-angle lips, indicated at 64 and 65, respectively, which lips lie in partial lapping relation when said sliding sash 52 is in closed position.

A horizontal cross shaft 66 is journaled in the side of frame 55 which is formed with the flange 62, and such cross shaft is of such length that it extends to, and is journaled in, the lip 64; said cross shaft being disposed substantially centrally between the top and bottom of such frame 55.

At its rear or outer end the cross shaft 66 extends out of the frame 55 and is there fitted with a finger knob 67, while within the confines of frame 55 the cross shaft 66 is attached to torque springs 68 which yieldably resist rotation of said cross shaft.

At its inner end the cross shaft 66 is fitted with a flat cam-faced latch 69 which projects toward the extension 63 and automatically catches with a keeper 70 mounted on the adjacent face of the lip 65.

When the sliding sash 52 is moved from its open position to its closed position-the latter being shown in Fig. 4-the latch 69 is deflected and then catches with the keeper 70 under the influence of the torque springs 68. To release the catch 69 it is only necessary to manually engage and part-turn the knob 67, whereupon the sliding sash 52 can be shifted to its open position. It is desirable and in fact necessary that the sliding sash 52, which is on the inside of the window, shall be capable of being readily removed so that its outer surface may be washed when necessary. To this end, the channel 44 in which the upper rail of the sash frame 55 slides is sufliciently deep that said frame may be shifted up so as to clear the bottom slide 57 of the sash frame from the sash track. This of course enables the frame 55 to be then shifted inwardly at the bottom so as to clear the channel 53 and the window frame generally, after which the sash may be pulled down clear of the upper channel 44. This may be done while the sash is in any other than a fully closed position. However, it is of course desirable to prevent said sash from being so manipulated from outside the window, and to this end the following arrangement is provided:

When the sliding sash 52 is closed, with latch 69 engaged with the keeper 70, the cross shaft 66 is received in a. notch 71 cut in the adjacent edge portion of the lip 65. At the same timei.e. when said sliding sash 52 is closed the upper outer corner thereof lies directly and closely below the top leg of the corresponding connector 49.

By reason of such engagement of the cross shaft 66 in the notch 71, and the described position of the upper and outer corner of the sliding Sash 52, it is impossible for such sash-even though the screen 35 be withdrawnto be removed from the window frame from the outside and by a person seeking unauthorized entry. Were it not for such an arrangement the sliding sash 52 could be shifted upwardly into the channel 44, clear of the channel 42, and then removed from the frame.

In order to drain the bottom channels 19 and 52 each independently to the outer portion of the sill plate 5, the following novel porting arrangement is provided:

The bottom of the U-shaped channel 19 is formed at a number of points in its length-with drain openings 72, while other longitudinally spaced drain openings 73 are formed in the adjacent flange 15 to establish communication between the channel 42 and said outer portion of the sill plate 5. With such arrangement, the channels 19 and 42 drain independently onto the outer portion of the sill plate, and without the necessity of any communicating passage between said channels, and which would be undesirable, as it tends to permitdue to hydrostatic pressureof blowback from one channel to the other, and thence to the inside of the window.

Also, the frame 37 of the screen 35 is formed with spaced drain openings 74 and 75 in the bottom and back thereof, respectively; the drain openings 75 being dis- 6 posed in a plane above the parting rail 16. Thus, any moisture which may be accumulated in the bottom of frame 37 is drained into the channel 19 and thence out of the latter onto the outer portion of the sill plate 5.

From the foregoing description it will be readily seen that there has been produced such a horizontal window with sliding sash as will substantially fulfill the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of such window, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.

Having thus described the invention, the following is claimed as new and useful and upon which Letters Patent are desired:
